Description

A kind of anti-drip irrigation zone of burning of double airfoil type
Technical field
The present invention relates to a kind of anti-drip irrigation zone (pipe) of burning of double airfoil type, belong to field irrigation infrastructure technique field.
Background technology
Drip irrigation zone is to be sent water by the aperture on diameter about 10mm hollow billets or water dropper using plastic tube (drip irrigation pipe is drawn) road Localized irrigation is carried out to crop root.Be by flow-out hole mouth very it is small enter water dropper or drip irrigation zone, water is drop by drop equal It is even and slowly drop in the soil near crop root.Drip irrigation zone is using polyethylene as primary raw material, by adding carbon black, increasing Modeling agent, the various auxiliary materials such as processing aid are prepared, and have the advantages that tensile strength is good, corrosion-resistant, electrical insulation capability, but phase It is corresponding it also there is non-refractory, the shortcomings of easily being burnt.Degradable mulch is using PLA as primary raw material, passes through addition The various auxiliary materials such as polycaprolactone, polyethylene glycol, talcum powder are prepared, have can voluntarily degrade, prevent under-film drip irrigation band from burning, Keep the effect of ground temperature.And existing this degradable mulch hydrophily is poor, when being covered on drip irrigation zone, on mulch film surface Droplet is easily formed, condenser effect is produced to sunshine because material surface forms droplet during high temperature direct sunlight, And drip irrigation belt surface is caused to damage.Researcher both domestic and external have also been made some contributions, and general idea is to improve degradablely The formula of film, make its surface that there is hydrophily, avoid material surface from forming droplet, but its method is excessively cumbersome, it is with high costs, It is unfavorable for popularization and application.
The content of the invention
Therefore, it is an object of the invention to overcome in the prior art the defects of, there is provided a kind of anti-drip irrigation zone of burning of double airfoil type, Both mulch film made of common degradation material can be used, and can enough effectively avoids drip irrigation zone from being sunlighted in droplet It is upper to form condenser effect and burn.
To achieve these goals, the anti-drip irrigation zone of burning of a kind of double airfoil type of the invention, including for conveying irrigation water Middle pipe and the water dropper for drip irrigation that is arranged on the downside of middle pipe, black degradable mulch is provided with above the middle pipe, The left and right ends of the black degradable mulch are connected in the middle pipe, have been also respectively connected with left and right sides of the middle pipe White degradable mulch.
The central region of the black degradable mulch forms gap with the middle pipe.
The gap maximum is distance 8mm.
The composition of the white degradable mulch, includes according to mass percent：PLA 50%, polycaprolactone 45%, Talcum powder 5%.
The composition of the black degradable mulch, includes according to mass percent：PLA 50%, polycaprolactone 45%, Talcum powder 4%, ordinary carbon black pigment 1%.
The composition of the middle pipe, includes according to mass percent：High density polyethylene (HDPE) 48%, low density polyethylene (LDPE) 25%, LLDPE 24%, carbon black 2.5%, PPA multifunctional concentrates 0.5%.
After the white degradable mulch, black degradable mulch, middle pipe are molded respectively, then once glued in hot sticky pick It is connected into type.
Using above-mentioned technical proposal, in the anti-drip irrigation zone of burning of double airfoil type of the invention, by conventional drip irrigation pipe with can commonly drop Solution mulch film is effectively combined together, and is disposably extruded, is blow molded by extruder, blow moulding machine, bonding forming, two kinds of different agricultures It is combined with technology (drip irrigation technique is with ground membrane technology), avoids the two separation adverse effect to caused by drip irrigation zone；Reduce Change the increased production cost of ground film formulation institute.By ordinary drip irrigation tape and extrusion forming of degradable mulch, it possesses drop Water saving effect of band and the automatic degradable of degradable mulch and effect that is keeping ground temperature are filled, drips modified polyvinyl chloride Filling band has excellent combination property, its compared with traditional under-film drip irrigation, saved manpower in the process of deployment of field into This, when carrying out mulch film laying, can completes the laying of drip irrigation zone；Because being bonded with black degradable mulch above drip irrigation zone, It can effectively absorb sunshine, so the anti-effect burnt can be effectively played, ensure drip irrigation zone service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As illustrated, the present embodiment provides a kind of double airfoil type anti-drip irrigation zone of burning, including for conveying in irrigation water Pipe 1 and the water dropper 2 for drip irrigation for being arranged at the downside of middle pipe 1, black degradable mulch 3 is provided with above the middle pipe 1, The left and right ends of the black degradable mulch 3 are connected in the middle pipe 1, are also connected respectively in the left and right sides of the middle pipe 1 It is connected to white degradable mulch 4.
The central region of the black degradable mulch 3 forms gap 1a with the middle pipe 1, to ensure to go out with good Water effect.
The gap 1a maximums are distance 8mm.
The composition of the white degradable mulch 4, includes according to mass percent：PLA 50%, polycaprolactone 45%, Talcum powder 5%.PLA 50%, polycaprolactone 45%, talcum powder 5% are added into mixed at high speed according to mass percent during preparation Mixed in machine, then be blow molded into white degradable mulch.
The composition of the black degradable mulch 3, includes according to mass percent：PLA 50%, polycaprolactone 45%, Talcum powder 4%, ordinary carbon black pigment 1%.According to mass percent by PLA 50%, polycaprolactone 45%, talcum during preparation Powder 4%, ordinary carbon black pigment 1% are added in high-speed mixer and mixed, then be blow molded into black degradable mulch.
The composition of the middle pipe, includes according to mass percent：High density polyethylene (HDPE) 48%, low density polyethylene (LDPE) 25%, LLDPE 24%, carbon black 2.5%, PPA multifunctional concentrates 0.5%.Will be highly dense according to mass percent during preparation Spend polyethylene 48%, low density polyethylene (LDPE) 25%, LLDPE 24%, carbon black 2.5%, PPA multifunctional concentrates Mixed in 0.5% addition high-speed mixer, then pass through extruder for shaping.
After the white degradable mulch, black degradable mulch, middle pipe are molded respectively, then once glued in hot sticky pick It is connected into type.
Table 1 is the contrast calcination situation of the anti-drip irrigation zone of burning of double airfoil type of membrane tube one：
Test period The drip irrigation zone of the present invention Common agricultural mulching
1 month Without phenomenon of burning Without phenomenon of burning
3 months Without phenomenon of burning Occur individually by aperture of burning
5 months Without phenomenon of burning Drip irrigation zone ruptures
Table 2 is the throughput rate situation of the anti-drip irrigation zone of burning of double airfoil type of membrane tube one.
Experimental Comparison time width Production Mean Speed of the present invention Prior art products produce Mean Speed
In March, 2015-August 80 ms/min 73 ms/min
Table 3 is the comparison production cost of the anti-drip irrigation zone of burning of double airfoil type
Contrast project The anti-drip irrigation zone of burning of double airfoil type Drip irrigation zone+anti-calcination degradable mulch
Drip irrigation zone cost of material 6500 yuan/ton 6500 yuan/ton
